So usually I'm pretty frugal... until it comes to art supplies/stationary. :( (I have a really unholy fetish for such things. Stick me in an art supply store, hell, even an Office Max! and I can wander around for hours on end.)
I finally cracked and bought an R4DS for my Nintendo DS just so I could paint on
DS Colors!" Also, with Colors you can make videos of the drawing process... it's really quite cool.

Then I discovered
this website and splurged $60 on sexy sexy sexy waterbrushes, watercolors, dip pens, waterproof ink... oh guilt! I had better actually use all this stuff instead of just packratting like I usually do...
